Abstract

The present disclosure relates to methods and associated systems for live streaming three-dimensional images based on images collected by two image collection devices. The method includes (1) receiving a first live stream from a first image collection device positioned toward an object at a first view angle; (2) receiving a second live stream from a second image collection device positioned toward the object at a second view angle; (3) determining a distance between the first image collection device and the second image collection device; (4) determining a view difference by analyzing pixels of the first image and the second image; and (5) generating a three-dimensional live stream of the object based on the first and second live streams, the determined view difference, and the distance between the first image collection device and the second image collection device.
